Notes:
1. Output load regulation is specifi ed for a load change of 20% to 100%. Units are available with 1.0 kV Isolation
2. Operation at no-load will not damage these units. However, they may not meet all specifi cations. See the datasheet for the MH1xxS-xx series
3. These converters will operate without external components. However, to meet the specifi ed EMI
limits, a simple external input fi lter is required. See the input fi lter note below for more information.
4. All units are rated for operation at full output power to +85°C. Operation over +85°C without airfl ow Mechanical Dimensions
is not recommended. Output power should be derated linearly from 100% at 85°C to 0% at 100°C.
5. It is recommended that a fuse be used on the input of a power supply for protection. See the Model
Selection table above for the correct rating.

Input Filter













The filter (C1, C2, C3 & L1) shown in the figure above
is required to meet EN 55022 level B. Recommended
component values are shown in the table at right. VIN C1 L1 C2 C3
(VDC) (µF) (µH) (µF) (pF)
Capacitor C1 is a 1210, 100V/ceramic, except for the Pin Connections
48V input which is a 100V/electrolytic. Capacitor C2 is a 3.3 2.2 18.0
1210 100V/ceramic. Capacitor C3 is a 1206 2 kV/ceramic. 5.0 2.2 18.0 Pin Description
12 2.2 18.0 1-VIN
To meet the requirements of EN 61000-4-4 and EN 61000-4-5 24 2.2 18.0 2.2 470 2+VIN
, the value of capacitor C1 should be changed to 470 µF/100V.
48 10.0 18.0 2.2 470 3+VOUT
All components should be mounted as close to the unit 4-VOUT
as possible.
MicroPower Direct Notes:
• All dimensions are typical in inches (mm)
• Tolerance x.xx = ±0.02 (±0.50)
We Power Your Success - For Less! • Pin 1 is marked by a “dot” or indentation on the top of the unit
